Note 037
From Chapter 45 of the Decline & Fall

I have described the state of Italy from the excellent Dissertation of Beretti. Giannone (Istoria Civile, tom. i. p. 374 - 387) has followed the learned Camillo Pellegrini in the geography of the kingdom of Naples. After the loss of the true Calabria, the vanity of the Greeks substituted that name instead of the more ignoble appellation of Bruttium; and the change appears to have taken place before the time of Charlemagne, (Eginard, p. 75.)
